For years I have said that my kids are not really like me. I have great admiration for my daughter. I always say she is nothing like me. One son has a lifestyle exactly like his father and his father's father. The other son is not like me. They were not raised by their father. Of course, there are some things similar to me, I am thinking now probably due to nurture, not nature. I had attributed the differences to several things. Not blood type. I don't know why. My children are in their 40's and A's like their father. I am a B.

In my family of origin, love them to death, we have certain qualities in common, but many more not in common. I have made different choices. I do different things than they do. I never attributed it to anything specific. I am a first born; thought maybe it had something to do with that.

Since finding out at age 58, through BTD, I was not the biological child of the man who, alone, raised me and my four siblings, (our mother was not in the home), and subsequently finding my bio father, it has been quite an awakening.

When I found out about my paternity, I knew right away before meeting him that whoever this person was he would be like me. My husband was very concerned about me approaching him. He was concerned that it might have a bad outcome. I had to travel across the US and go to him alone, before calling or writing him. Long story. I told my husband and a couple of friends that knew at this point, not to worry, he must be like me because I am not that much like my mother or dad.

Sure enough, I am a blue print of this father of the same blood type. We are both entrepenuers, make the same choices in foods, have the same life styles, etc. (I posted about his passing away last month). It is amazing to me to learn certain things that I would never have thought are inherited. I have always been very much a believer in environment having more to do with how a person "turns out" vs nature. Changing my mind.

My family of origin are mostly blood type A, my mother is an O. Most of the kids that are A, are so much like my dad who is an A. One sister, an O is just like my mom.

You know how you hear of several kids in the same family, how one is successful, one a drug addict, one this, two that, whatever? And we say, well everyone in the family does not have the same experience in that family? That is true, but I wonder how much of it has to do with blood type and inheritance of personality traits of the family.

I am wondering if others can see this in their families. I would say kids would have to be grown, making their own lifestyle choices to see much of this. We are not sure how younger kids are going to make choices in life yet.

My "new" dad's wife was so shocked to see that I tie my tennis shoes just like he does, who ties his different that anyone else. She had never seen anyone tie their shoes like him besides me. Who would think that could be an inherited thing? I had a discussion with one sister I was raised with while driving across country for a visit with new dad. We were listening to music. She and I have different tastes. We tend to talk on a subject for a long time while driving; makes the time go by faster. Anyway, I had spent the last day telling her that I like songs I can sing to, certain songs anyway, and we talked that subject to death. When I got to new dad's for my second visit with him, I asked him what kind of music he liked, he said "songs I can sing to". We spent a few hours that day picking out songs on youtube. We both liked the same things. And he sings around the house, something I always do, but not my family of origin.

How many of you can see this in your families? Are you more like the parent with your blood type, if you have a parent with your blood type. Do you have habits/lifestyle like uncle joe who happens to be an O like you, if your parents are not O? We know bloodtype and personality are related. I am not asking if you are more outgoing like the O's in the family because you would likely be more outgoing like the neighbor who is an O. I am thinking about whether you are driven to write, or more daring, or hate change, lived in the same house all your life, have alcohol/drug addiction tendencies, a clean freak, mental illness issues, like songs you can sing to vs hard rock, can't sit still, a home body, creative, etc, like your parent/relative with the same BT.

According to the studies of twins, personality is about 50% inherited and 50% environmental. Since we are all individuals those percentages are just averages, some people take more from one than the other.

I am quiet like my dad, but bit more outgoing than him, same is true for my three other siblings even though I know at least two of them are Os, not As like me and dad. ( The other one is a geneticists and will not discuss BT with me lol, I suspect he is an A). Mom, the O, is a wild thing, at 83 her schedule is full and she is always on the move and anything but quiet!

“Tomorrow is the most important thing in life. Comes into us at midnight very clean. It’s perfect when it arrives and it puts itself in our hands. It hopes we’ve learned something from yesterday.”

Very intriguing topic! I am fairly new to this way of life ( a few months now) and love it! Now I'm really curious to find out what blood type my parents are! I seem to have many more similarities to my father than my mother and it would be interesting to find out if blood type has anything to do with it!

My immediate family is all Os. Mom who is controlling matriarch says I am different from family when in fact I'm not. My dad says I am like him which is true, we are both Virgo INTJs. My sister sides with mom & says my dad is weird. Parents are divorced. My dad is not weird, nor eccentric really. We appear to be an adversarial Hunter group, overly reactive to each other & ever on the lookout for potential threats. No one understands this except me. I talked to my sister actually wrote her in email. She told me to go off this diet, have something healthy like kashi go lean with a bunch of blueberries & milk.

The Japanese have long studied the connection between blood type and personality, as Dr. D has also commented on.

Recently I saw a video on YouTube (http://youtu.be/T3hveKfmXtg) showing an experiment with kindergarten children, who are divided into the 4 groups according to their blood types. Each group goes into a room, where they are told that the vase in a corner is a very important gift from the headmaster and no one should break it. Then, a teacher breaks the vase deliberately to see how the kids react.

Type A kids are very worried and some go out the door to seek the headmaster to report on the event. Type B kids start laughing and think the whole situation very funny. Type O kids burst out in righteous anger and accuse the teacher for wrongdoing. Type AB kids do irrelevant things and promise to keep this a secret. But as soon as the headmaster comes into the room, they tell her the secret! The experiment shows how differently people of different blood types react to the same situation. Interesting, eh?

So I think there really is some connection between our blood type and personality. In my family, I have always exhibited traits similar to my dad, who shared the same blood type as me. My brother, however, is a very different personality. He and my mom have the same blood type, B. However, I have picked up certain traits from my mom just because she and I were very close when I grew up and I picked up her way of thinking and reacting to the environment. So in my case I would say it's 50% nature and 50% nurture.

I was pretty intrigued by Dr D's blood type personality information in his books when I first started reading them in the 90's. Subsequently, I purchased and read several other books about blood type and personality, also read about it online.

I find the studies interesting. I can see that we have things in common those of the same BT, in general.

I guess I am more asking about life patterns or passions of people that we are related to; have our lives gone more in the direction of the parent or relative whose blood type we share, that share other contributing factors like DNA, nurture, culture, location and life experiences that grey rabbit and RedLilac touch on as opposed to the person next door who shares our BT.

I agree RedLilac, we are all unique. One of my favorite things to have learned following BT.

Yes..50%nature and 50% nurture! Many studies done over decades involving twins and adopted children.I am an only child with the same blood type as my Mom but have many "explorer" tendencies like my O- Dad. Mom is emotional and dramatic (in a good way...she's funny) and Dad is more reserved and a "thinker" yet definitely speaks his mind! Both are friendly, loving and very family/traditions oriented. My husband and sons say I am "excitable" and love to cook like my Mom but want to "run the other way" when Dad and I get into a deep discussion..he like politics/religion. Dad is always Mom, Dad and I are all huge outdoor/garden/animals/pets enthusiasts. Dad has to keep busy, Mom likes to "chat" outside on the chair swing.I have my Mom's coloring but my Dad's build.I guess i am pretty much half of one and the other...

My family is all very similar: happy natured, aggressive, physical, argumentative, busy bodied, can be trivial but always to the point, cuts to the chase, direct. My dad likes to think & take things apart like I do; my mom & sister are more energetically self satisfied & tend to think they know it all.

The more meat I eat, the happier I am. As a kid I danced, was a joiner, talked constantly & liked to giggle. I'm more like that now as an adult on this diet than I was in my 20s.

My dad has been deceased for a very long time. He was an O+, like me and I inherited the rare Mg antigen from him. I think the g in Mg stand for Gilfeather, my maiden name. Anyway, my mom is an A+. Most people think I look more like my mom than my dad, although my coloring is not like either of their's.

Personality wise, my dad was a very negative person. He always was resentful of people and things and particularly resentful of his children as they achieved more than he. My mom is much more warm and loving and revels in her childrens' successes. My parents separated when I was in the sixth grade. My dad was very difficult to live with, so all of us were relieved when he left. Sad but true.

While I share my dad's blood type and rare blood antigen, I have always been a very positive person. Living in a house with a very negative dad, it was very difficult for me to really discover my true self, as sometimes the environmental influences can have a strong impact on personality.

I met my husband when I was 25. He is the most positive person I have ever met (a type O), even more positive than my mother. His positive, happy influence really helped me to be the person I was meant to be and express my positive, happy personality.

I think in my family, I do not fit the theory that you are more like the parent with whom you share blood type, and for that, I am grateful.

Both of my daughters are O-, and they're as different as night and day. I'm similar in temperment to my younger daughter,and both of us are similar to my Type B+ son. But DD1 is just a different breed. The three of us explode easily and then calm down just as fast. But DD1 is super-sensitive to stress in her environment- we yell and then it's over 2 minutes later, but she's stewing about it for hours because that minute of yelling upset her equilibrium.

This makes for a lot of household stress. We feel like we're "walking on eggshells" around her so we don't set her off, and she feels like we're a wild bunch with no stability. We often joke that she's "the white sheep of the family" (and the rest of us are the black sheep.)

She and I are both O Gatherers. I'm not sure about the genotype of the other two, although I'm pretty sure I can rule out Hunter for DD2.

None of these generalizations about blood type and personality seem to make any sense with my family. Gender/personality stereotypes don't make sense either, unless you want to simply say that DD2 was more boyish as a young child. It just throws the whole nature/nurture argument out the window. Both girls got pretty much the same foods in utero and in young childhood. Both have the same biological parents and blood type. They were raised in the same home, went to the same schools, etc. But they're as different as night and day.

I wish I had known decades ago that I would be my fathers daughter.. never occurred to me.. what a difference it would have made can only be conjectutred..

I was living to far away to see him often enough to even discuss his life or mine, so only after he past on, that I see the inherited trates and potential for illness...

at least I know now, and can see what I will do with my life.

first I have to lose 40 pounds.. but whenever I even use those words I just eat more..

The future will tell me more.. but just having printed out my Swami so I can re-read in peace is going to matter much.. I just need to be able to underline and highlight some things on paper.. no other way to retain pertinenet info..

I expect to learn more here on this collumn.. have not read all the posts but find it interesting as my adopted (reversley) girl is the same Blood type, Secr type and Gatherer for sure.. but she is way of worse in every weight category.. I am awaiting her maturing to be able to learn more about it all.. she does no longer live with me and so much wrong food and to much weight.. yet so much younger.. so maybe so much more time to fix her food issues.. thanks for the sharing of new ways to look at..

Being here is invaluable, but not enough. We need ALL the Doctors. I needed them for a very small cancer spot-I could never feel!!! Please do your mammograms! Doing so saved me from cancer later on. I am grateful! Thanks for learning from my experience! I was lucky! I wish the same for YOU!

None of these generalizations about blood type and personality seem to make any sense with my family.

I know we have had a lot of these personality discussions before and I am not sure exactly what I am trying to get at or at least I think maybe I am not making my question clear.

Your kids are younger (than my 40 yr olds anyway). I was thinking more about the directions our lives have taken as we got older, choices, preferences and not really personality, per se. Also, I was thinking more about later in life. When we are younger we haven't yet set our course.

I was telling of how my "new dad" with my blood type was an entrepeneur. I didn't become one until I was 34, so I could not have said my life followed his course until later in life. In fact, if anyone took a look when I was young, I definately was not going in his direction. Another interesting thing (to me at least) is that we both went to 3 different high schools, due to circumstances out of our control, both quit high school and both became successful, me an RN/inventor, he a building contractor/owner of a commercial hardware supply chain. The family I was raised in, didn't have any of those.

I think looking back when you are old like me it is easier to see a pattern, maybe not identical, but a similar course, if there is one. Maybe, maybe not. I am just wondering outloud because of the events that have taken place in my life.

I have mom's tendency to worry and religious devotion, and dad's mechanical aptitude and interest in learning how to do a little bit of everything.

What are their blood types?

I know you lived in NC, TJ. Were you a distance away from your parents? Did one of your parents move a distance from their parents? It is things like that I am thinking about. Patterns of lifestyle, kind of things. Preferences, passions. You may have to get old like me to see which one's life you may have more in common with.

so only after he past on, that I see the inherited trates and potential for illness...

at least I know now, and can see what I will do with my life.

Yes, Goldie. It may take looking later in life to see what I am talking about.

One of my sisters is 48. It is here lately that I can see her life taking the same path of our mother, who has just passed away. They are the only two O types in the family and she is more and more like my mom. I may not have said that when she was younger, although they have always been more firey than the rest of us.

I never thought about that... I lived appart from him most of my life, but he moved often as I do easy, he might indeed have had many attributes that I saw in my mother but through a different lense I might actually have seen some of my own actions as resembling my fathers??????? gosh what a can of worms you openeend.... but I think I got a dose from all my fore-going family.

the biggest contrast is my sis who I guess to be a B .. there are differences, but not in character as much as in the lenght of hair we have - meaning all the day to day stuff.. there we function best leaving each other to our own devices.
